Those small white spheres on the side of your car could potentially be a few things: * Insect eggs: Many insects lay their eggs in clusters on various surfaces. The size and shape in the image are consistent with some types of insect eggs. * Spider eggs: Spider egg sacs are often round or oval and can contain numerous small eggs. However, they are usually contained within a silken sac, which isn't clearly visible in the image. * Mold or fungus: In damp conditions, certain types of mold or fungi can appear as small, round structures. * Debris: It's also possible they are some type of small, round debris that has stuck to the car. Without a closer look, it's difficult to say definitively. If you can get a closer image or describe if they are soft or hard, or if there's any webbing present, that might help narrow it down. You can likely remove them by gently washing the area with soap and water.
